Abstract: A positive electrode and a battery employing the same encapsulant composition are provided. The positive electrode includes a positive electrode active layer and a first layer, wherein the first layer is disposed on the positive electrode active layer, and the first layer includes a lithium-iron-phosphorus-containing oxide and a first binder. The electric resistance ratio of the first layer to the positive electrode active layer is greater than or equal to 100.
